IMPRovEMENT iN oFF-BEARING TRUCKS Fon 'BnicK-Mlicnines.

I The Schedule referred to in these 'Letters Patent and making part el' the sai-ne.

To all whom it may concern Be it known that I, WALKER OLDs, of Albany, in the coulity of Whitesides alid- State of Illinois, have invented certain Improvements in Off-bearing Trucks to be use-d in connection with Bi'iek-itlacliines 5 alld I do liel'eby declare that the following is afull, clear,

aiid exact description thereof, reference. heilig had to the annexed drawings making part of thisl specification, in which- Figure l is a side elevation of a portion of a bricl machine and of an attachment thereto, designed for usetin receiving the bricks .from such machine, and iol' transporting tlie'in to the kilil or to any o ther tlcsired locality; and

` Figure 2 is a plan or top view of the same, showingihe aprons upon which the bricks are received as they lscribed hereinafter,

A ill the drawiilgs refers to a plunger or presshead, which is for the purpose of pressing ol' forcing the bricks outot the molds in which they are formed and placing them upon the truck.

In practicotherc will generally be two trucksatiached to' one bricklpressing machine, such trucks being arranged iipoil each side of the point' where the bricks are pressed', so that 1the molds may be shifted from the position which they occupy when the bricks are pressed to the proper positions for liavilig the` bricks pressed out of them upon the trucks.

B refers to a traine-work, which receives the reciprocating press-heads or' plungers, they heilig constructe'd andarraiiged as shown in a patent granted to me on the 13th of July, 1869, against which the bricks are formed as they are pressed into the molds, said frame-work being so constructed vor iormedthat an attachmentcali be readily made with projecting pin on side of truck, as showli ill g. l.

C refers to au arm or spring, which is to be .attached to the plunger A in such a manner as to partake ot' its longitudinal movement as it presses the bricks from the molds.

From the point where it joins the plunger it ci@ tends forward for a distance suliicieiit to permit its outer end to come in contact with Vand operate the rod or bar E, soon to be described, its outer end heilig provided with a hook or pin for connecting it with such rod or bar.

D D refer to the side bars of the truck, their distance apart being such as to permit of the apron being of such a width as to receive upon it as many bricks as are contained in one mold.

These bars are provided with pins iii their outer sides to forni an attachment to the frame-work B, and thus prevent the truck from heilig pressed away from suchy iframe while the bricks are heilig deposited there- 4 .llielouter ends of these bars are iliade to assume the forin'of handles, for the purpose of enabling the operator to grasp thcni in moving the truck.

Upon the outer sides of these bars there are to be attached legs, upon which the outer end of the truck rests, and near their inner ends arms or standards, which form the bearings for the wheels upon which the-truck is moved, as clearly shown iu fin'. l of the drawings.

D' refers to an apron, upon which the bricks are delivered as they come iiolll the molds, it being made to move by being .passed around rollers or-cyliiiders placed near the ends of the bars D, and having .their bearingstliercin. l v i Small wires are inserted between the fibers of this apron, or are otherwise attached thereto, which extend across it tralisverscly,and are for the purpose of keeping it of equal width in all of its parts as it passes around the rollers upon the truck.

l)2 refers to springs, of which there are two, one upon either, inside of the bars or frani'e D, they heilig coiled around a shaft, and having their ellds secured to said frame in such a manner that as their outer ends, ol' those, parts which carry the roller D, are pressed upon the apron DI, which passes beneath such rollers, they sci-veI to tighten such apron, and thus keep its upper surface siiiootll for the reception of the bricks. y

E E refer to sliding hars of met-al, which are placed upon theo'utcr surfaces ofthe bars D, they being ai'- ranged as shown i-ii fifi. 1, or so that as the truck is placed in the position there shown their forward ends shall engage with the pins or hooks upon arms G, and thus have their movement communicated to, them.

It will be observed that the front ends of these bars are curved upward', the object of which is to provide the means of ready attachment to the arms O, and

that from this point they extend back through staples, in which they slide, aiidby which theyale supportedv and guided, to near the handles of the truck, where they come in colitact with ratchet-wheels E E', upon the elids of the shaft, which carries the outer cylinder or roller over which the endless apron passes.

As a consequence of the lastfdcscribed arrangement o i' parts, the movements of plunger A is communicated to the ratchet-wheels E E', land through them, and the roller or cylinder to which they are attached, to the apron, which is thus' made to move the proper distance to receive each discharge ot` bricks as they come from the molds, and carry them outward until the apron is filled, when, by disconnecting the sliding bars from the arms C, the truck muy be taken to any desired locality.

The* truck is ,disconnected from the machine by raising its outer end by the handles, thereby depressing its inner end, and' disconnecting the projecting-piu, and also pressing down the spring C, detaching itfrom Having thus described my invention, v What I claim, and desire to secure by Letters Patent, is-
